Question: Is whole food vitamin C superior to natural because it is part of a tyrosinase complex? Short Answer: Vitamin C is nearly ubiquitously distributed in plant tissues, and is never bound to any enzyme as a structural complex. Vitamin C promotes absorption of iron from plant foods, inhibits copper absorption, and de-loads copper from ceruloplasmin, which may play a role in distributing copper to tissues. Vitamin C is not capable of destroying ceruloplasmin. These functions follow directly from vitamin C as an electron donor and there is no evidence whatsoever that whole food vitamin C behaves differently in these respects than synthetic vitamin C. However, daily needs in most contexts are 2-400 milligrams of vitamin C per day, which is below the dose shown to potentially cause problems with copper. Getting this from whole foods or whole food supplements is better than using synthetic vitamin C because it avoids GMO corn and Chinese synthetics and provides a host of other beneficial constituents alongside the vitamin C.

Question: What Is the Real Issue With Seed Oils? Short Answer: The main issue with seed oils is that they present an oxidative liability. They do not acutely cause oxidative stress, but their polyunsaturated fatty acids (PUFAs) are more vulnerable than any other macronutrient to oxidative damage. Oxidative stress can increase because of nutrient deficiencies, toxins, infections, other sources of inflammation, alcohol, or smoking, and it will inevitably increase as a function of aging. As oxidative stress increases, more PUFAs in the tissues mean more damage. At least 0.6 milligrams of vitamin E should be gotten per gram of PUFA in the diet, but vitamin E cannot fully protect against PUFA, so their intake should be moderated to the very low levels needed, as obtained by eating fatty fish once or twice a week, eating eggs daily, and eating 4-8 ounces of liver per week. Additional secondary problems with them include residual solvents and heat damage prior to intake, but the main issue is that we do not want to increase our tissue PUFA content more than needed.

Question: How useful is hair trace mineral analysis (HTMA) for nutritional testing? Short Answer: Hair trace mineral analysis is included as an optional add-on in the comprehensive nutritional screening from Testing Nutritional Status: The Ultimate Cheat Sheet, because it can capture data for some ultra-trace minerals for which there are no better-validated tests, and it might capture a pattern that might not be picked up as quickly with blood work, such as a mineral transport issue. However, its utility is limited by the fact that hair mineral content is not well validated as a test for any specific mineral, is generally anti-validated when there is enough science on a mineral (such as zinc, where hair zinc does not go down in deficiency), and should not be used as a central piece of data without corroboration from other more well-validated tests, which exist for most of the nutrients.

Question: How to Find the Root Cause of Autoimmunity? Short Answer: Autoimmune conditions are likely driven by deficiencies of vitamins A and D, which contribute to post-infectious autoimmunity by compromising the rhythmic rise and fall of myeloid-derived suppressor cells (MDSCs), and to autoimmunity regardless of infections through impaired suppression of Th17 helper T cells. More broadly, infections and tissue damage are the most likely drivers of autoimmunity onset. However, energy metabolism governs everything through the second law of thermodynamics, which holds that energy must be used to prevent everything from randomly mixing, and this includes randomly mixing the immune defense against pathogens with immune attacks on the host. In this example, we discuss how a respiratory chain disorder would compromise absorption and distribution of zinc and compromise the oxidation of NADH to NAD+, and how both of these would interact with a genetic impairment in acetaldehyde dehydrogenase to prevent the activation of vitamin A to retinoic acid. Autoimmunity thus results as one of many symptoms of vitamin A deficiency driven not by lack of vitamin A, but rather by impaired activation of vitamin A, secondary to impaired energy metabolism.  This is a clip from a live Q&A session open to CMJ Masterpass members.

Is high-dose vitamin C good for you?   High-dose intravenous vitamin C can selectively kill cancer cells in live patients and can save sepsis patients from dying, but it acts as a pro-oxidant in cancer and an antioxidant in sepsis.   So what does it do in the rest of us?   Oral doses of 2000 milligrams raise oxalate levels in most people, and as little as 400 milligrams raises oxalate in some people.   This seems to be the most sensitive indicator of a delicate imbalance with glutathione and other factors needed to recycle vitamin C. Such a balance actually needs to be avoided when killing cancer yet is critical to maintaining health in every other context.   Given that vitamin C is important to immunity and general health, how do we take advantage of these benefits without upsetting the delicate balance with glutathione and the propensity to generate oxalate?   That is the topic of this podcast.   This podcast is a preview of a video only available to Masterpass members.   Get evergreen access to the video and podcast, as well as the written article with references, here:   https://chrismasterjohnphd.substack.com/p/balancing-vitamin-c-and-glutathione-d6f

Question: Why Would Vitamin C cause muscle pain, joint pain, and brain fog? Short Answer: Acutely, vitamin C would likely cause these effects by generating oxalate, which could cause crystals that lead to muscle and joint pain, and could cut energy metabolism in half, leading to brain fog. This vulnerability could result from deficiencies of any of the B vitamins, any of the electrolytes, or of iron, copper, or sulfur; from diabetes, low adrenals, or hypothyroidism; or from any of the hundreds of genetic defects in energy metabolism, only one of which is glucose 6-phosphate dehydrogenase deficiency; or any one of a huge number of toxins that impair energy metabolism. Chronically, vitamin C may increase the harms of iron overload or contribute to copper deficiency. The main ways to manage these latter issues are to take vitamin C away from meals, to maintain good copper status through proper dietary intake, and to treat iron overload with phlebotomy.

If you are eating a high-protein diet, you probably aren't getting enough biotin. This is especially true if you are a protein-fueled athlete and find your skin too oily, too itchy, or too red; if your blood sugar is getting out of control; or if you simply feel down in the dumps. And it's especially true if you find your hands or feet tingling or get subtle sensations of something crawling on your skin. Alternatively, if you're pregnant or looking to conceive, this is something you really need to understand. This is a free preview of an episode reserved for Masterpass members.

The use of high-dose biotin supplements has increased almost 30-fold over the last twenty years for such problems as diabetes, smell and taste disorders, disorders of the hair, skin, and nails, and multiple sclerosis. Studies show it can improve diabetes, and case reports show it can miraculously recover lost smell and taste even when smell and taste were lost as a result of surgery or the side effects of medications or other supplements. Yet, some studies show multiple sclerosis gets worse on high-dose biotin. I personally developed clumsiness, short-term memory loss, and a short temper on high-dose biotin. Some studies show it makes blood sugar get better, yet it made my blood sugar get worse. High-dose biotin can also cause wide-ranging errors in lab tests with the potential to mask recent heart attacks, pregnancies, or allergies; to misdiagnose thyroid conditions; to give false signals about the presence or progression of tumors; to falsely raise vitamin D, B12, and folate levels; to falsely alter many hormone levels; to generate false positives for HIV and hepatitis; and to lead to unnecessary surgery and possibly even death as a result of diagnostic errors. Most people need more biotin than they get. Some one in 30 people need high-dose biotin for genetic reasons, and most other people should be getting lower doses. So, how do we know how much we need, and whether we are getting the right amount? When is the right time to break open the bottle of the ten-milligram capsules? This article covers the safety and efficacy of high-dose biotin for all the conditions documented in the literature, its potential anti-fertility effects, and how and when to balance it with other vitamins.

Question: Can NAC hurt your gut health? Short Answer: N-acetylcysteine or NAC can be used at a dose of 600 to 2,400 milligrams per day for 5-10 days to disrupt biofilms and make it easier for antimicrobials to kill bacteria. Animal studies suggest that acute doses up to 6 grams do not deplete mucus or cause ulceration, but that an acute dose of 17.5 grams can deplete mucus and cause ulcers within two hours. Human studies suggest that 10 grams per day can be used for 24 weeks with fewer than 1 in 6 people complaining of gastrointestinal side effects. Yet, chronic use of NAC will thin the mucus, disrupt the biofilms used by normal healthy microbiota, and possibly deliver excessive sulfur to certain components of the microbiome. Therefore, I would not use it except for specific, targeted reasons, and I would not use it at a dose higher than needed or for a duration longer than needed.

Question: How can I protect against oxalates? Short Answer: Getting 300-400 mg calcium between food and supplements at each meal will minimize oxalate absorption. Maintaining postprandial urine pH in the 6.4-6.8 range by getting 3-5 grams of potassium per day from food or from organic acid salts such as potassium citrate will prevent its crystallization in the kidney. Reducing dietary oxalate will prevent any possible damage in the gut. This is a clip from a live Q&A session open to CMJ Masterpass members.

Question: Why should postprandial blood glucose be kept under 140 milligrams per deciliter? Short Answer: When blood glucose rises above 140 mg/dL, this is the approximate point at which it spills into the polyol pathway at a greater-than-normal rate, which represents a suboptimal state of metabolism that is likely to hurt antioxidant status and compromise detoxification pathways as well as the recycling of vitamin K and folate. It must be kept in mind that a healthy person will adapt to glycemic loads they consume regularly. Thus, a one-time spike above 140 mg/dL should never be used to conclude anything whatsoever. Only repeated spikes above this level with repeated consumption of the same glycemic load over several days to several weeks should be used as a cause for concern.

Question: What is the relationship between copper and estrogen? Short Answer: Estrogen moves copper from the mother's bloodstream to the fetus during pregnancy. Its action at the intestines is poorly understood but I believe estrogen and progesterone interact to promote intestinal copper absorption. Maintaining pregnancy-level hormones while not pregnant poses a risk of promoting too much absorption of copper from food without transferring it to a growing baby. Copper status should be monitored when using supplemental hormones to avoid copper toxicity. This is a clip from a live Q&A session open to CMJ Masterpass members.

Question: How to slow graying of hairs and potentially reverse it? Short Answer: What works for any given individual will likely be to find the weakest link and fix it, from among the following systems: the signaling of energy abundance (body fat, insulin sensitivity, thyroid hormone, adequate protein, individualized meeting of carbohydrate needs, good management of psychosocial stress, supporting neuroendocrine signaling with copper, vitamin C, zinc, and glycine, and supporting thyroid function with iodine and selenium); the biochemical infrastructure of energy production (all the B vitamins, iron, copper, sulfur, magnesium, potassium, and managing genetic idiosyncrasies impacting energy metabolism), and antioxidant protection (protein, vitamin C, vitamin E, zinc, copper, selenium, iron, and manganese).

Question: How much iron can we absorb at once? Short Answer: High-dose iron will produce more total absorbed iron, but will also leave more in the gut, which could cause constipation or disturb the gut microbiome. If desperate for quick relief, 200 milligrams per day of iron taken in the morning will work faster than lower doses or the same dose taken in the afternoon. For most people, however, I believe it is best to start with 18 milligrams of iron, and only increase it to 27 or 36 milligrams, or higher, if needed. If it is difficult to raise iron with a supplement, try eating a temporary carnivore diet that includes egg yolks but not whites, or at least try taking your iron with a breakfast that matches this description.

Question: What cofactors are needed to synthesize and recycle BH4? Short Answer: Zinc, magnesium, potassium, and niacin are the cofactors needed for the synthesis and recycling of BH4. Folate and methylation are not involved, though high-dose folate or folic acid could hypothetically hurt BH4 recycling since both are recycled by dihydrofolate reductase (DHFR).

Question: Is it important to get vitamin D sulfate specifically from the sun? Short Answer: It is important to get morning outdoor sunlight as close to every day as possible for your circadian rhythm, and to get some exposure to unprotected sunlight during the day when UV is available, but at doses less than needed to cause reddening, and it is equally important to always avoid burning. There are many reasons for this, and the cholesterol sulfate hypothesis — to which the vitamin D sulfate hypothesis is peripheral — is an interesting and worthy hypothesis but should not be the final arbiter of your sun exposure habits.

Question: If a person has a hereditary weakness for Branched Chain Amino Acid Catabolism would this impact the type of diet they might choose to loose weight? Should they limit protein if it will increase their need for nutrients like Biotin?What are all the possible cofactors we should consider supplementing to support Leucine catabolism? Short Answer: Metabolizing branched-chain amino acids requires all B vitamins except folate, calcium, magnesium, potassium, and chloride. If you have a genetic impairment in this pathway, then reducing branched-chain amino acid intake and doubling down on cofactors is important during weight loss because the pathway will be stressed more in the catabolic state.

Question: If I don't want to hurt my omega 6 status through my omega 3 intake, how do I do that? Is it simply a question of taking them at separate times? Or is it a question of dose? And if it is a question of dose, how do I know when to start eating fish and taking my omega 3 supplement again? Short Answer: How they are combined in meals is not important, but it is important not to have too much EPA in cell membranes relative to arachidonic acid, and this is driven by cumulative intake over years. For someone who has consumed too much EPA for many years, the best approach is to eat liver and egg yolks for arachidonic acid while getting omega-3s from a DHA supplement and not from fish, fish oil, or fish liver oil.

Question: Can plant foods and their phytochemicals be used to reduce arterial plaque? Short Answer: Yes, but if you don't have specific intolerances to plant compounds the best thing to do is simply aim to meet your vitamin and mineral targets from a diet rich in fruits, vegetables, herbs, and spices, rather than trying to use specific plant compounds from specific studies in any specific amount.

Question: What can be done about twitching? Short Answer: Most twitching will be driven by glutamate/GABA balance or acetylcholine regulation, and the most likely nutritional issues are any of the electrolytes or any factor that influences energy metabolism. The best way to address it is to consider the conditions that influence it and then trial and error your way through each potential nutritional issue in order of which ones make the most sense for your individual case first.

Question: If undercarboxylated osteocalcin has health benefits, and vitamin K2 decreases it, what does that mean for K2 supplementation? Short Answer: Vitamin K2 helps secure osteocalcin in bone matrix, where it is decarboxylated and released as an endocrine hormone in response to certain stimuli. When released, it acts to optimize insulin secretion, insulin sensitivity, fuel use during exercise, and male testosterone. This is a clip from a live Q&A session open to CMJ Masterpass members.

Question: If I'm at risk of heart disease and phosphatidylcholine increases my TMAO, should I stop the supplement? Short Answer: On a scale of one to ten, my concern about TMAO and cardiovascular disease is a three. There are thousands of things that should be given equal weight as potential contributors to heart disease, but TMAO gets the most attention because the Cleveland Clinic has an incredible PR machine to spread their research, which serves to bolster their financial interest in marketing the test. That said, it is not a universal necessity to supplement with phosphatidylcholine. If you are concerned about your TMAO, you can try substituting trimethylglycine (TMG), and ultimately judge the value of each supplement by whether it is helping you in a demonstrable way.

Question: How do I fix low blood sugar on vegan keto? Short Answer: Consider how important it is for your ketones to be elevated. Most likely you need to eat more protein, which will lower your ketones. I would aim for a minimum of 0.8 grams per kilogram of ideal bodyweight and consider using 1.2 grams per kilogram of ideal bodyweight. If this does not work, consider all of the nutrients involved in energy metabolism — all of the B vitamins, iron, copper, sulfur, magnesium, potassium — but especially biotin and B6 for their disproportionate role in gluconeogenesis. If the protein you need to normalize your blood sugar does reduce your ketones to a level that are not giving you the benefits you are looking for, you could consider raising them with exogenous ketones.

Short Answer: Plasma zinc is the single most important marker of zinc status. Urine zinc may decline faster in deficiency. Hair zinc increases with supplementation but does not decrease in deficiency. Plasma zinc is decreased by inflammation, oxidative stress, the ovulatory and luteal phases of the menstrual cycle, probably pregnancy and oral contraceptive use, and any kind of stress that leads to an adrenal output. If plasma zinc declines despite supplementation, corroborate that this reflects zinc status by showing normal hair zinc and low urine zinc. Use symptoms as the ultimate arbiter of whether zinc supplementation is helping. This is a clip from a live Q&A session open to CMJ Masterpass members.

Short Answer: It could be byproducts of any of the three amino acids that make up the glutathione molecule, which include the individual amino acids, ammonia, hydrogen sulfide, sulfite, and propionyl CoA, or it could be microbial metabolites of glutathione produced in the gut.

Short Answer: From the trials, statins seem to reduce heart disease risk and total mortality, but it is impossible to separate this from conflicts of interest and industry funding. There are plausible mechanisms by which they may hurt mitochondrial function and promote soft tissue calcification. Dietary sulfur appears to lower cholesterol. While Lester Morrison showed 1500 milligrams per day of chondroitin sulfate could reduce cardiac events 7-fold, this has a theoretical potential to hurt the microbiome. My preferred way of getting sulfur is 1.2-1.8 grams per kilogram bodyweight of total non-collagen protein, with an emphasis on animal protein.

Short Answer: I believe most methyl donor intolerances are a result of deficiencies in the glycine buffer system, which requires glycine, vitamin A, fasting (glucagon), androgens, riboflavin, unmethylated folate (THF), and iron. No one should expect to tolerate 30 milligrams of folate, however, and there is almost never a reason to use doses that high. This is a clip from a live Q&A session open to CMJ Masterpass members.

Short Answer: The main problem with too much protein, particularly animal protein, is that acidity may hurt the bones and increase the risk of calcium oxalate kidney stones, but this can be obviated by balancing it with organic acids, which have bicarbonate-sparing effects that are alkalinizing. The best index of the organic acid content of foods is the potassium content. This balance can be achieved with 750 to 1500 milligrams of potassium for every 100 grams of protein. This is not specific to whey protein. Other than allergies, none of the claimed harms of whey protein are convincing. This is a clip from a live Q&A session open to CMJ Masterpass members.

High-dose biotin supplements can cause a multitude of false lab tests, masking recent heart attacks, pregnancies, or allergies, giving false signals about tumors, and far more. In this episode, I lay out for you the nature, scope, and magnitude of the problem, and develop actionable strategies you can use to protect your lab tests from generating false information as a result of this phenomenon. You can find the written and fully referenced version of this episode here: https://chrismasterjohnphd.substack.com/p/biotin-causes-false-lab-tests The written version also contains some figures that help you visualize the mechanistic information.

This will encourage the Substack algorithm to get it in front of more people. In High Protein? You Need More Biotin, I made the case that 30 micrograms per day is not enough for adults, and that many people need 150-300 micrograms per day, depending on how much protein they eat.

Short Answer: Energy metabolism in general declines across the body with aging, but energy metabolism seems to stay healthy enough in the brain in people who do not experience cognitive decline. Cognitive decline does appear to be driven by decreases in brain energy metabolism, but these are not best described as a specific impairment in glucose handling. MCT oil can be modestly beneficial and a ketogenic diet can probably be somewhat more beneficial in people who have cognitive decline from any type. There is no evidence to support using it as a preventative. For prevention, I believe we should focus on aerobic fitness, nutrients required for healthy energy metabolism and antioxidant defense, and maintaining metabolic health with a healthy body composition and a healthy physical activity routine that includes the proper spread of a portfolio of different types of exercise.

Ordinarily reserved for Masterpass members, my PUFA report is free for everyone TODAY ONLY. This was a paid report I wrote for subscribers in 2008, and I have updated it with new reflections. It is well worth taking in now in 2022, in my view, so check it out today while it's free! My original intention was to investigate the claims of physiologist Ray Peat that the essential fatty acids are not essential at all. I came away from my research believing that they are, in fact, essential, but that mainstream textbooks and reviews made several serious errors. One was that they grossly inflated the requirement. Another was that they missed the most important point, that the requirement is far lower when supplied by animal fats, especially liver. My most stunning discovery was that the omega-3 fatty acid, EPA, might not even be a normal constituent of the mammalian body. I stand by this discovery and it has shaped my view of modern omega-3 research ever since. You will likely find many nuggets in this report surprising. Listen today while it's free!

I am done with my work on COVID vaccines, at least until I finish my Vitamins and Minerals 101 Book, so I am now making my scientific review on the likely causes of COVID vaccine side effects public. This is an excerpt of pages 19-52 of my Healing From COVID Vaccine Side Effects guide (free to Masterpass members here). You can read the written version on Substack using this link, which contains 139 of the 221 references. It does not contain the protocol, but rather the scientific review used to judge the mechanisms most likely underlying the side effects. Since I am no longer working on this, I hope it proves useful to anyone doing further work on the topic. This was originally published on August 10, 2022. The science described is not intended to be comprehensive. Rather, emphasis is placed on what is likely to provide insights into the mechanisms of side effects.

Short Answer: While protein restriction may have value in people with established cancer or kidney disease, cycling robustly between fasting and feeding states is likely to provide all the value that restriction of protein or calories might otherwise provide, and a high protein intake supports bone mass, muscle mass, and the detoxification of carcinogens, all of which are important to longevity.

Short answer: Low or low-normal alkaline phosphatase may raise the plasma B6 level over the cellular level. Tryptophan metabolites in urine reflect the B6 requirement for the kynurenine pathway, and this requirement increases with more estrogen, more inflammation, or a higher protein intake.

Short answer: 4-6 hours after a meal the small intestine is emptied and the insulin-to-glucagon ratio declines; 25 hours after, hepatic glycogen is emptied; 5 days later the brain is adapted to ketones and gluconeogenesis reaches its minimal level. Moving from one to the other cannot occur with a small piece of signaling like the bite of an apple. It requires the preponderance of signaling.

Short answer: Probably not. Animal studies showing a difference use huge doses in an unrealistic context. Human studies show they don't at doses used. Human effect on PSA is vulnerable to regression to the mean and thoroughly unconvincing.   This is a clip from a live Q&A session open to CMJ Masterpass members.

This new model I developed explains how the depletion of arginine and tryptophan and the sequestration of cysteine leads to T cell suppression in severe COVID and may reflect the rapid onset of a somewhat cancer-reminiscent state where vitamins A and D and other myeloid differentiation factors run out. The written version with references and links to research is available here: https://chrismasterjohnphd.substack.com/p/a-new-paradigm-for-severe-covid If you find this valuable, please like, share, and comment on the Substack article to help boost it within the Substack algorithm and get more people to read it. Vitamins A and D should be properly balanced with each other, and with vitamins E and K. My COVID-specific recommendations for this balance are in the COVID Guide, and recommendations for balancing them in various different contexts are included in the Vitamins and Minerals 101 Cliff Notes, both of which are freely available to paid Substack subscribers. These also contain general (Cliff Notes) or COVID-specific (COVID Guide) information for managing all the other nutrients mentioned. I will be updating the COVID guide next time to include tryptophan and N-acetylcysteine whenever arginine is used, but other than that this new paradigm does not alter the protocol. It does, however, move much more emphasis to A and D, and bring A onto much more equal footing with D. Disclaimer I am not a medical doctor and this is not medical advice. My goal is to empower you with information. Please make all health decisions yourself, consulting sources you trust, including a caring health care professional. Paid Subscriptions, Coming Guides, the Book My current plan is to wrap up a vaccine side effect protocol and my general work on the vaccines into a COVID Vaccine Guide that will be free to those who have pre-ordered my book, Masterpass members, and paid Substack subscribers. I will then do one final update to the COVID guide, also free to everyone I just mentioned. Paid Substack subscribers and Masterpass members will also have access to all paid-only Substack posts, which are the posts that feed into the creation of the vaccine side effect protocol. Most of these will be available for 48 hours to everyone. You can become a paid Substack subscriber here, which earns you 50% off the fee on Masterpass membership if you choose to join. The book can be pre-ordered here. As soon as these two guides are finished I will return full-time to finishing the book and will send everyone who pre-ordered an ETA as soon as I am ready.

Short answer: You should be able to see changes on imaging within a few weeks if your approach is working well, but ultimately this is entirely dependent on how negative your “delta fatty liver = (fat in) - ((fat out) + (fat burned))” equation is.

Short answer: 25(OH)D is 1000 times weaker at activating the VDR than 1,25(OH)D, but 1000 times more abundant. This is why I advocate measuring both, and ultimately believe we need to create a calculated index of “biological vitamin D activity” from them.
